Title: Commutation circuit of thyristor
Inventor: ISHIDOU MICHIHARU
IPC: H03K17/732
Filed: 1977-11-26
Abstract: PURPOSE: To obtain a commutation circuit of short commutation time which empolys a saturable reactor with its iron-core area made small, by making the voltage- time product vary with the polarity of a current flowing to the saturable reactor.  
     CONSTITUTION: Saturable reactor 8 is devided into winding parts 8a and 8b by being provided with a center tap. At the turn-on time of reverse-conduction thyristor 5, the voltage-time product for operating both winding parts 8a and 8b increases. When current I s  is inverted, the voltage-time product decreases since winding part 8b is shorted by diode 9 and, in consequence, the magnetic flux is reset. Consequently, the magnetic flux can be used effectively by suppressing di/dt at the turn-on time, and the surge voltage and dv/dt at the reverse recorvery time without making large the iron-core sectional area of the saturable reactor.
